Significance Electrochemical reduction of CO 2 can convert CO 2 emission back to value-added fuels and chemicals and store renewable electricity. Reducing CO 2 to multicarbon products has attracted great interest because of their higher energy densities and associated economic values. We report here a promising strategy for steering CO 2 electroreduction toward ethanol production by exploiting a surface-bound Ru polypyridyl carbene catalyst on an N-doped porous carbon electrode. We show the synergistic effects of Ru polypyridyl carbene for CO intermediate production with a porous carbon for C–C coupling that could boost ethanol production at relatively low overpotentials. The strategy provides insights on how to improve selectivity and efficiency for CO 2 reduction toward multicarbon products.
